, INTERMITTENTLY-OIPERATED GAS-VALVE.

To all whom it may concern:

Be it known that I, Frans J OHAN HENRIK Rns'rron, a .subject ofthe Kingof Sweden,

residing at LillaEssingen, Stockholm, Sweden, have invented new anduseful Improve- V ments, in Intermittently-Operated Gas- Valves, ofwhich thefollowing is a 'SpeClfir. cation.

I The present invention relates to means for repeatedly interruptingagas current and isv particularly adapted for producing inter-- mittentlight'in signaling devices, saidmeans being capableof efiecting a veryuniform periodicity inits action. This property is due to the fact thatthe member controlling the interruption consistsof aLmember oscil-'lating like a pendulum and being'kept in motion by. theproper action ofthe escaping gas. For instance the member may consist of a springactuated balance oscillating around an axis or of a common form ofpendulum, or finally it'may always'rotate in the same direction but inthe same time be made according to the principle of a fly ball governorso that some part thereof at the rise of speed, caused by the escapinggas, changes its position under the influence of the centrifugal forceand returns when'the speed again decreases.

In the accompanying drawing,- Figure 1 shows one form of the: inventionin a; vertical section'and Fig. 2 a corresponding plan view with thecover of the casing removed; Fig. 3 a second form of the invention in avertical section; Fig. a'corresponding plan view with the cover of thecasing removed;

Application filed January 17, 1914. SerialNo. 812,848.

apparatus is inclosed in a casing l, the inlet 2 of which is controlledby the valve 8, while the outlet 4 is free. T hevalve 3 is arranged in abushing 5 so as to open inwardly and is provided with a pin 6 projectingoutside said bushing. Around a spindle 7 journaled centrally inthecasing 1 a balance 8 is capable of oscillating under the action of aspiral spring 9. 'lnis balance has a projection 10 which lies in thepath of the pin 6 so as to strike the latter and open the valve. Whenthis is done, a quantity of gas flows out into the casing l and impingesagainst the projection 10 and thus rotates the balance against theaction of the spring. Then the gas escapes through the outlet & where itis ignited for instance by a pilot flame for efi ecting a flash oflight. The balance swings as far as permitted by the tension of thespring and then returns, whereupon the same operations are repeated. Inthis-manner a very exact and also easily controllable periodicity of theflash light can be obtained, while at the same time the periods of lightmay be made very short which is of importance for saving gas. Forincreasing the elfect of the outrushing gas current on the projection 10the lattermay be made dish shaped, as shown.

In the form shown in Figs. 3-5 the oscillatory member also consists of abalanceS movable around a spindle 7, but instead of a fixed projection10 this balance here carries two weighted arms 11 which are swung outmore or less underthe influence of the centrifugal force. This enablesthe balance to be swung more than one revolution at a time, as atasuflicient speed of said balance the arms 11 are lifted above the valvebushing 5'so as to pass the same-freely. Only when the speed hasdecreased to a certain extent by the action of the spring, one of thearmsll hits the pin 6 which is here bent upward, so that a quantity ofgas can escape.

On account of the oblique direction of the outlet port 18 (see Fig. 5)this gas is directed obliquely upward so as to strike the weight of thecorresponding arm lland swing the arms again. Otherwise this form islike that already described. This arrangement may also be modified inthe manner illustrated in a plan View by Fig. 12. The valve casing herehas two chambers in which two valves 3 are movable so as to open inopposite directions. Each valve is provided. with an upwardly bent pin 6asthesingle' valve in Figs. 3-5, and thus one valve or the'iother isopened depending upon the side, from which the, parts are struck-by thearms 1 11 which are similar to those shown in Figs. I 3-5. Otherp'arts'are also the same jas'in' these figures.

"In-"Figs; 6 and 7, there is used, instead of a balance, a swingingpendulum 12, a construction Whichas also that shown in Figs. 3 andl'of:.course only may be used'when the apparatus assumes a certain fixedpo;

sition, viz. that shown'i'n the drawing.- The valve proper shouldybesim1lar;tothe forms I described. before, and its pin' should of coursephragm l4 to which the? pin 6 ofthe valve,

be in the swinging planeof the pendulum.

F igs. Sand 9-show a construction which diifers from that shown'in Figs;l and2 sub Stantially inthat the. escaping gas does not directly actuatethe projection 10$ of the balance,.but fills a'space'lalimited by" a.diais. secured, so that the said ,pin at the eX- pansion of thediaphragm pushes .forth the 1 balance substantiallysimultaneously .with

. emanating fromthevalve 3 actuates a small the closing of the valve.From the space-l3, the gas fiows directly to theoutlet 4; thusit neverfills the chamber in which the balance swings whence said chamber maywell be in communication with the open air. 7

Finally in Figs. 10 and 11,.the-gas or fluid turbine wheel 15 secured toa rotatablespindle 19. I On the same spindle there are fixed twoswinging weighted arms 11 which in a of time; Also in this way theopening of. 1 the. valve may thus beeflected at. fixed '1n-.

. small'bell crank lever 16 the othcrarmbf' which normally holds. the.pin 6 with they valve 3 down. Hereby the valve is opened for a moment,and the fluid then escaping through the nozzle 17 increases the speed'ofthe turbine wheel so thatthe arms 11 will be;

lifted above the lever 16 for 7 another period I Having .nowparticularly described the nature ofmy invention and the manner of.
